Fix:
throw new CommandFormatException ( ( ( ( ( ( "Content<seq2seq4repair_space>file<seq2seq4repair_space>doesn't<seq2seq4repair_space>exist<seq2seq4repair_space>" + ( f . getAbsolutePath ( ) ) ) + ",<seq2seq4repair_space>" ) + ( pathCompleter ) ) + ",<seq2seq4repair_space>windows=" ) + ( Util . isWindows ( ) ) ) ) ;
